This would also mean by the time you get to the end of the first main quest arc regarding the Empire, you should have a firm grasp of the game and have been at lvl 50 for quite a while.

Note to new players coming in:

Do your class quests. All of it. And start on your relic.
At the end of A realm reborn, you're going to face your first 8-men dungeon. Be prepared to run fast, or be left behind.
Once you get to Hard mode dungeons, you're going to have to team up with people who have zeta and top gears. Be prepared to spam agro , spam heal and AOE.

For the love of God above, announce it if you're new to something. People will understand but there will always be butthats, so just grit your teeth if someone bash on you. Most of the vets know you're new by the way you handle your class.
